摘要：The packaged food product includes a food product and a package enclosingthe food product The package is formed from a coated, printed film that includes asubstrate film including one or more thermoplastic materials and having an averagethickness of less than about 0.38 mm (15 mils). An image is printed on the print side ofthe substrate film. A radiation-cured varnish covers the printed image. The radiation-cured varnish was formed by coasting the printed image with a radiation-curable varnishthat includes one or more polymerisable reactants and optionally one or morephotoinitiators. The radiation-curable varnish is subsequently exposed to radiationsufficient to polymerise at least 90 weight % of the polymerisable reactants. In oneembodiment, the radiation-curable varnish comprises less than 20% monofunctionalmonomer based on the weight of the radiation-curable varnish. When the coated, printedfilm is tested according to the FDA migration test protocol, no more than 50 parts perbillion total of any of the polymerisable reactants and the optional photoinitiatorsmigrate within 10 days at the 40°C from the coated, printed film into a food simulant of95 weight % ethanol and 5 weight % water enclosed within a test container formed fromthe coated, printed film so that the food simulant contacts the food side of the substrate
film and the ratio of volume of food simulant to surface area of coated, printed film is 10millilitres per square inch. In another embodiment the package comprises one or moreheat-sealed regions and at least a portion of the radiation-cured varnish extends into theheat-sealed region;and wherein the weight of the radiation-cured varnish per unit area ofsubstrate film in the portion of the radiation-cured varnish extending into the heat-sealedregion is at least substantially equal to the weight of radiation-cured varnish per unit areaof substrate film outside of the heat-sealed region.
